Hi everyone,
we are currently having a problem with getting a grid to a .tiff format using
Vertical Mapper.
Let me explain the situation.
In mapinfo, we are using a mapbasic app with one functionnality of the app is to
export a grid to a tiff file using the vmExportGrid function from vertical mapper.
Opening the resulting tiff file poses no problem with mapinfo.
But we need to get this file open in arcview so when we use a script of arcview to
convert the .tab of the tiff to a world file of arcview (creating a ifw file), the
projection of the tiff looks to be all wrong when viewed in arcview.
The thing is that if we go thru Vertical Mapper dialogs, and select tool-export-tiff,
the conversion of the tab file to worldfile for arcview (this time it creates a tfw
file) the projection of the image when viewed in arcview is fine.
When we look at both .ifw and .tfw, they are identical in their content so I'm
thinking it must be something with the .tiff file itself.
I'm guessing there must be something when using the vmExportGrid in mapbasic that must
be done before exporting the tiff so that the projection should be fine of the tiff
file itself.
I don't see what could be creating the problem except the projection when exporting
the grid to tiff format. Problem is that the vmExportGrid does not take any parameter
in conjunction with a CoordSys....
vmExportGrid(Grid_ID, FileFormat, FileOutput, NullValue, ProgressBarAdress)
Does any one might have an idea of how to get this situation resolved?
Thanks
Mat
